"Buying a horse soon !!!" she wrote in her return to social media Aug. 16. "So many options it's kinda hard !!! A horse called Sophie and another called Roar ??? I can't make up my mind !!!"
Her mysterious message continued, "Should I join the camaraderie and put a pink cowboy hat on ??? Either way I think I found my sweet spot with Roar !!!"
Britney, 41, also shared a photo of herself, dressed in a yellow bikini top and black denim shorts, while riding a horse on the beach.
Earlier in the day, a source familiar with the situation confirmed her and Sam's separation to NBC News, adding, "It's best for Britney."
The actor—whose next project is Grand Death Lotto—filed for divorce from the pop star the same day, citing "irreconcilable differences" as the reason for breakup and listing their date of separation as July 28, 2023.
The couple was the subject of breakup rumors in March, after they were both seen sans rings. However, Sam's rep, Brandon Cohen of BAC Talent, cleared up the rumblings at the time, telling E! News that they were not having marital issues.
In fact, the rep went on to explain the only reason Sam took his ring off was because of a work shoot.
"First day filming," Sam captioned an on set selfie March 20. "But for which project? Stayed tuned."
The small, star-studded ceremony included guests like Paris Hilton, Selena Gomez, Drew Barrymore, Madonna and Donatella Versace, who also designed the "Toxic" singer's wedding dress. As for her bling? Britney's engagement ring featured a four-carat diamond in a platinum setting, with the word "Lioness"—Sam's nickname for her—engraved on the band.
The nuptials marked Britney's third trip down the aisle as she was wed to childhood friend Jason Alexander for 55 hours in 2004 before marrying Kevin Federline—with whom she shares sons Sean, 17, and Jayden, 16—later that year. The two divorced in 2007.
At the time of their engagement, a source close to Sam told E! News that marriage was always in the cards for he and the "Gimme More" artist, especially as her 13-year conservatorship was coming to an end.
"Things are evidently becoming better for Britney with her conservatorship and she's never felt this liberated in all aspects of her life," the insider shared. "The closer she gets to freedom, the closer she is to seeing all of her dreams become an actual reality. Marrying Sam is high on that list and loving him the way she wants, how she wants, on her own terms. Sam also understands how close they are to being out of the woods, and it's definitely motivating him to think big."
